Abstract：

Cosmic ray studies started more than a hundred years ago, with countless articles and numerous textbooks published. Advanced numerical codes have been developed to describe cosmic ray propagation and acceleration, and, at first glance, the field reached not only its maturity, but even its old age. Thus, it is shocking to find out the fundamental processes that were missed by the generations of earlier researchers or were incorrectly described.To support my point, I will discuss a few topics that I have worked on. Those include perpendicular super diffusion, mirror diffusion,acceleration, and the Levi flights of cosmic rays.
